It depends on what you mean: 1) just farther than we can currently see in our observable universe or 2) outside ofour Universe.
1) Very, very far away, farther than we can currently observe:
To the best of our current observations and theory, the Universe on the largest scales is homogeneous (i.e. 'smooth', or of similar density, composition, etc.) and isotropic (it looks the same in every direction). So, no matter where you are within our Universe, it should be about the same. That's the short answer.
Let me point out that our Universe has a finite and well-determined age; recent measurements put it at a little over 13 billion years (roughly 3 times the age of the solar system/Earth). There is a limit to how far away we can see--13 billion light-years--because the universe is only 13 billion years old, and light from farther away hasn't had time to get to us yet. This DOES NOT mean that the Universe is only 13 billion light-years in radius, and we are at the center of it; it is only our observable universe that is that size. As time passes, the size of our observable universe increases at the speed of light.
The actual size of our Universe is much larger; we just can't see it. So, to an observer farther than 13.4 billion light-years from us, outside our observable universe, things probably look about the same as they do here, but we won't know for sure until enough time passes for light (and gravity waves, neutrinos, whatever) arrive from there for us to observe.
Note that is is an assumption--that everywhere is about the same as it is here, and we're not at the center of the universe*(see below for why astronomers think this). This assumption is true for the amount of the universe we can observe, so most astronomers assume that it is true in general.
Expansion of the universe
How do we know we're not at the center of the universe? We observe the light from distant galaxies to be redshifted, which means that the galaxy is moving away from us very quickly. (Look up the Doppler effect; we hear the same effect from a moving sound source, such as a police car siren getting lower in pitch when the police car is moving away from us.)
Light from almost every galaxy, except those nearest to us (Andromeda, the Virgo cluster) is redshifted, meaning that everything is moving away from us, except for a few nearby galaxies. We can conclude that either: a) we are at the center of the universe, or b) space itself is expanding, and everygalaxy sees most other galaxies moving away from it! We think it is b), that space is expanding. You can understand this in two dimensions by taking an uninflated balloon and marking some dots on it. Now, inflate the balloon. Every dot gets farther away from every other dot. Our universe works the same way in three dimensions.
So, that brings up the question---if our Universe is expanding, what is it expanding into?
2) Outside our Universe: The cheap answer is that we can never know, since by definition it is beyond our universe. That's the best answer we can currently give, based on observations and generally-accepted theory.
There is no 'edge' to our Universe; even if you were able to somehow able to travel faster than light, and go beyond our observable universe, you would never encounter an edge, no matter how far you looked. Likewise, the Earth is finite in size, but there is no edge to the Earth; it's a curved surface. Mathematicians would call this a 2-dimensional surface of positive curvature, embedded in 3 dimensions---you can travel around the earth, and eventually end up where you start. The universe works the same way, except that it is a three-dimensional curved surface embedded in four (spatial) dimensions. Just like we can't find the center of the Earth anywhere on its surface, there is no center to the Universe that we can find, because we are stuck on its 3-dimensional surface; the center is in a higher dimension. (I know that sounds bizarre!)
Incidentally, current observations show that our universe has negative curvature, the opposite of a sphere; (it will expand forever, and you could never travel in one direction and end up where you began like you can on surfaces of positive curvature such as the Earth).
As for what the fourth spatial dimension is that we can't observe because it is OUTSIDE OUR 3-D Universe, it is beyond what current science can answer. Read the numerous other answers to this question below for other peoples' thoughts on this.No one knows whats on the Other Side of the UniverseThe answer to the question "What is on the other side of the universe" is very simple, that is, no one knows yet. But perhaps if we were to wait about 500 or more years maybe, and just maybe, there will be some sort of respectable answer based somewhat more on accumulated facts than on imaginary theories.
How would we know? Are we ever GOING TO GET THERE? Well, build a time machine and go into the future so we can see if we will, but we can't do that right now.The Other Side of the UniverseRecently it has been observed that the farthest objects we can see are not only traveling outwards at great speed but also accelerating. (It is my personal belief that) God gave the galaxies their initial thrust but to be accelerating there must be some other force being exerted too. One feasible explanation is that there are similar bodies near enough to pull the outer regions of our Universe outwards. These bodies would be part of our universe, but perhaps not observable to us from our vantage point. Another explanation being taken seriously is a repulsive force that we have not yet observed that would be pushing the outer galaxies farther and farther away. AnswerThere is no other side of the universe. The four dimensional geometry of space and time is such that wherever you are in the universe seems to you to be the center. However, the universe seems to be fairly homogeneous. Wherever you are you would find mostly empty space with galaxies of stars consisting mostly of hydrogen, and planets orbiting the stars.

These things are so enjoyable to ponder. We are so locked in to our amazingly tiny view of the universe relative to both space and time that we are surely not yet open to some Very Big Ideas that will 'change' everything. At one time, intelligent thinking people could not fathom the idea that the earth is a globe moving in an orbit around the sun. People once considered it obvious and common-place that animals sprang whole from various kinds of plants. Surgeons didn't hesitate (it was a brutal business back then) to cut into people without even a simple soap and water wash of their hands, or of their instruments. Even into the 20th century, some were convinced that travel to the moon and other bodies in space was absolutely and fundamentally impossible-- not because of technology but because of natural unbreakable limits and laws. People are just now 'getting' that time is relative.
Regarding the 'edges' of space, people are probably right who argue that no matter where you are you will appear to be in the center. One of those Very Big Ideas (that I make no claim to understand) is that the 'border' of space is itself three-dimensional, and therefore not reachable in anything like a conventional sense. We move in three dimensions, so there is no place we can go, and find ourselves in something other than a three-dimensional space. There is really nothing 'beyond', unless you break through the tiny theorized dimensions locked fast in the mysterious quantum. Even then, anyplace else that could possibly exist would not be 'outside' of our universe but parallel to it.
We haven't even mentioned the possibility (there is evidence in support of this) that space itself is expanding, and this may in part account for the redshift in our observations of distant galaxies.
no way. because universe is so huge it has no end at all
Pure white light then it starts over on the other side of the universe.
Everything in the universe. things on the other side of the universe are affected by earth's gravity, but so slight that it isn't recognizable.
a gogleplex years. it is a number with so many zeros that you wouldn't have enough space in the universe to write it all out
In the law of physics, yes there are multiverse of universe, but there is no evidence that there are other universe.
There is nothing above below or in the side of the universe as it keeps expanding.
there could be a whole new universe or just takes you into a different place in space or they don't end at all
First of all, there are no "sides" to our Universe, unless you want to refer to "that infinitesmally small part of our Universe that we can presently see" as "the Universe." The totality of our Universe has no center, thus it also has no "side." There are, however, "parts" of our Universe, and not all parts can see all other parts. In our case, we can only see objects about 46 billion light-years* away, meaning we see only a VERY small part of the total Universe. It's because there's only been 13.78 billion years for any light from any object to travel towards us. That means any object whose light would have needed 14 billion years to reach us, won't be seen by us. * Yes, 46 billion ly, not 13.8 billion ly. The reason that we can see that far is a bit technical, but is a consequence of our expanding Universe.
I am not aware of any distinction, in astronomy, between a "light side" (or whatever) and a "dark side". The Universe isn't really divided into "sides". Of course, the farther away you get from stars, or galaxies, the darker it will get.
To you and me, probably very important since we live in it. I am not sure our solar system is very important to life forms on the other side of the universe.
It looks to us as if we were in the middle of the Universe; probably from any other position, it would also look as if you were in the middle of the Universe.It looks to us as if we were in the middle of the Universe; probably from any other position, it would also look as if you were in the middle of the Universe.It looks to us as if we were in the middle of the Universe; probably from any other position, it would also look as if you were in the middle of the Universe.It looks to us as if we were in the middle of the Universe; probably from any other position, it would also look as if you were in the middle of the Universe.
no. a universe is everything. so technically theyre arent other universes.
Yes it is a possibility if it was true.
that is not known the big bang theory says the universe is always expanding. that raises the question what is around the universe? since we havent ever visited the side of the universe (and we probably never will) so there is no answer to your question
If you mean the 'other side' of a black hole, we don't really know. The other end of a black hole could be a rabbit hole, spitting matter into a parallel universe. Or perhaps there is no other side and matter is simply gone. Many believe it is possible that black holes could be gates into other universes or parallel worlds. However, since we haven't thrown anyone into black holes, we don't know what lies on the other side.
A Hypergiant is found on the out side the universe
The Universe is bigger. The Universe encompasses everything we know; it isn't known whether there are other universes.
Singularity, Beginning of the universe, or is there a beginning of the universe, existence of other universe
The universe does not have a name. In other words, the universe is just called the universe. Only the stars and the planets have names.
Yes. So is every other location of the Universe.
There are billions and billions of other galaxies in the universe.
The Earth affecting us is one side of the question. Humans affecting each other is another side. Humans affecting each other due to the Earth is also another subject. We are affected by the Earth, by the Moon, by the Sun, and all of us affect each other by human reasons and by the Solar system reasons, and finally by the Universe reasons.
